The Critical First Step for Many Bay Area Electrical Projects: PG&E Applicant Design is a process where a qualified, pre-approved designer (like GridSync) creates the engineering plans for your utility connection. You likely need it for any project that increases your electrical capacity—like a 200A panel upgrade, adding an ADU, or installing an EV charger. It’s the key to getting PG&E approval and avoiding project delays.
If you’re planning a major electrical project in the San Francisco Bay Area—whether it’s upgrading your home’s electrical panel, adding an Accessory Dwelling Unit (ADU), or installing a solar + battery system—you’ve likely encountered the term “PG&E Applicant Design.” It sounds technical, but it’s simply a crucial step in getting your project approved and connected to the grid.
Many homeowners and even general contractors are unfamiliar with this process, which is a leading cause of frustrating and costly project delays. This guide explains exactly what PG&E Applicant Design is, when you need it, and how partnering with a qualified designer like GridSync can save you time and headaches [citation:1][citation:4].
This guide is specific to projects within PG&E’s service territory, which includes San Francisco, San Mateo County, Santa Clara County, and most of the Peninsula. The rules and processes can differ for other California utilities like SCE or SDG&E.
What is PG&E Applicant Design?
PG&E Applicant Design is a program that allows a pre-qualified, third-party designer—not PG&E—to create the engineering drawings and specifications for the utility-owned portion of your electrical or gas service installation. In short, a qualified firm takes on the responsibility of designing how your home will connect to the main power grid [citation:1][citation:4].
This program was launched in 2018 in response to a California Public Utilities Commission (CPUC) decision. The goal was to streamline the process for new and upgraded utility connections by distributing the design workload and ensuring high-quality plans from the start, which minimizes the number of back-and-forth reviews by PG&E [citation:1][citation:2].
What Does an Applicant Designer Actually Do?
A qualified PG&E applicant designer is responsible for a comprehensive set of technical documents. This is not a simple sketch; it’s a formal engineering package. According to PG&E’s requirements, the design must include [citation:1][citation:5]:
- Detailed Drawings: Gas layout drawings, single-line diagrams (key sketches), base maps, construction details, and joint trench drawings.
- Complex Engineering Calculations: These are critical and must be signed and stamped by a registered Professional Engineer (PE). They include calculations for voltage drop, flicker, short circuit duty, pulling tension, pole sizing, and guying [citation:1].
- Material Specifications: A detailed material list for components like transformers, conduits, and meters, broken down by location and referencing PG&E’s rules (e.g., Rule 15, Rule 16) [citation:1].
- Site and Permit Information: Identified rights-of-way, required permits, and coordination with other utilities [citation:1].
How the Applicant Design Process Works
Understanding the workflow helps you see why a qualified designer is so important. Here’s a simplified step-by-step of the process [citation:4][citation:5]:
Application & Intake
You or your contractor submits an application for service through PG&E’s “Your Projects” online portal. PG&E assigns a representative (Job Owner) who will be your point of contact [citation:5][citation:9].
Design by Qualified Designer
Instead of PG&E designing the project, you engage a PG&E-qualified applicant designer (like GridSync). Our team visits the site, performs engineering analysis, and prepares the full design package, including all necessary drawings and calculations [citation:1].
Submission to PG&E for Review
We submit the completed design package directly to PG&E’s Resource Management Center. PG&E then reviews the plans to ensure they meet their current design standards and safety requirements. This review typically takes 1-3 weeks [citation:1][citation:5].
Approval & Proposal
Once PG&E approves the design, they provide you with a project proposal, contract, and an invoice for any applicable engineering advances or meter charges [citation:5][citation:9].
Construction & Inspection
After you sign the contract and make payment, construction can be scheduled. The physical installation is often done by a separate qualified contractor (an “applicant installer”) [citation:2]. After installation, local city inspectors and PG&E sign off on the work before your meter is installed and power is turned on [citation:5][citation:9].
Do You Need It? Project Scenarios
Whether you need the full Applicant Design process depends on your project’s scope. In many cases, for a simple like-for-like panel replacement, you might not need it. But for any project that increases your home’s electrical capacity or requires changes to the utility service, it’s almost always required [citation:4].
✅ You Likely Need Applicant Design
200A or 400A Panel Upgrade: Increasing your home’s amperage nearly always triggers the need for a new utility connection design.
Adding an ADU: A new dwelling unit requires its own electrical service or a substantial sub-panel, demanding a new load calculation and utility design.
New Service for EV Charger: If your panel is at capacity and you need a new 40-50A circuit, this may require a service upgrade and therefore applicant design.
Overhead to Underground Conversion: Changing your service type requires a completely new design.
New Construction: Any new home build needs a new utility service design [citation:4].
❌ You May Not Need Full Design
Like-for-Like Panel Replacement: If you’re simply swapping an old 100A panel for a new 100A panel with no increase in load, you may qualify for PG&E’s “Express Connect” process, which is much simpler and faster [citation:4].
Small Repairs: Fixing a weatherhead or other minor service repairs usually don’t require a new design.
💡 Key Takeaway: If your project is on the left side of this list, you need a qualified applicant designer. Choosing one with in-house engineering, like GridSync, is the most efficient path forward. For a deeper look at the electrical work these projects entail, see our guides on 200-amp panel upgrades and ADU electrical requirements.
The GridSync Advantage: In-House Qualified Designers
The most common source of project delays is a rejected PG&E applicant design. This happens when contractors without proper qualifications submit incomplete or incorrect packages. GridSync eliminates this risk because we are a PG&E-qualified applicant designer with in-house Professional Engineers. We handle the entire engineering process, ensuring your submission is accepted the first time [citation:6][citation:8].
Applicant Design vs. Applicant Installation
It’s important not to confuse Applicant Design with Applicant Installation. They are two separate qualifications in PG&E’s program, and a company may be qualified for one, both, or neither [citation:1][citation:2].
| Role | Responsibility | Qualifications |
|---|---|---|
| Applicant Designer | Creates the engineering design, drawings, and calculations for the utility connection. This is the “planning” phase. | Must pass PG&E’s qualification exam and demonstrate proficiency in design software, engineering standards, and PG&E’s specific requirements [citation:1][citation:6]. |
| Applicant Installer | Performs the physical construction work—trenching, laying conduit, setting substructures—according to the approved design and PG&E’s construction specifications (the “Greenbook”) [citation:9]. | Must be pre-qualified by PG&E through the Industrial Training Services (ITS) program to ensure they can safely build the utility facilities [citation:2]. |
GridSync is qualified for both. We can design your project and build it, providing a single point of responsibility and accountability. This avoids the finger-pointing that can happen when a design firm blames the installer or vice-versa.
